The Caterham Seven 420 is available in a single trim with an R Pack available as an optional package. Power is supplied by a Ford-sourced naturally-aspirated 2.0-liter four-cylinder engine mated to a five-speed transmission. Power is sent to the rear wheels, and the powertrain develops 210 hp and 203 lb-ft of torque. The standard car features a standard chassis size, road suspension pack, 14-inch alloy wheels, as well as a fully carpeted interior, black leather seats, and a heater, amongst others. The R Pack includes features such as a limited-slip differential, lightweight flywheel, a sport suspension pack, and a four-point racing harness. Optional features include a six-speed manual transmission, a fire extinguisher, and lowered floors. For taller drivers, Caterham offers a larger body size that will accommodate drivers and passengers of up to 6’6” in length.
